What is a heat transfer film?

Heat transfer film It is an indispensable material in the heat-transfer process. This process requires applying heat and pressure to the heat-transfer film once, thereby transferring the design from the film onto the surface of the decorated object.

Throughout the thermal transfer process, the protective layer and the graphic layer separate from the polyester film under the combined action of pressure and heat, allowing the entire pattern coated with hot-melt adhesive to adhere to the substrate. The surface of a thermal transfer film consists of a base color layer, a protective layer, a release layer, and a hot-melt adhesive layer.

By applying the heat and pressure generated by the thermal transfer machine, the transfer foil is bonded to the surface protection layer, the decorative wood‑grain print layer, and the base color layer, causing these layers to separate from the polyethylene and transfer onto the surface of the engineered board or the designated area requiring hot stamping, thereby creating a decorative pattern. As a result, this surface exhibits excellent properties such as heat resistance, abrasion resistance, and lightfastness; its color tone remains highly stable, and its patterns are both innovative and aesthetically pleasing, making it widely used in the market.

How to assess the quality of heat-transfer film: Meijiao shows you how to identify PU. Heat transfer film The quality isn’t simply a matter of so‑called experts deeming it good or bad. Therefore, evidence demonstrating the product quality of PU heat‑transfer film is required. There are three key aspects to consider:

Operational issues in 1.1. PU heat-transfer film: Is the lettering film easy to engrave, cut, and remove waste material?

2.2 Thermal transfer issues. PU Heat transfer film : The convenience of lettering film thermal transfer and the issue of waste disposal.

3. Will No. 3. PU Heat transfer film Heat‑set or not: This relates to the washing process—specifically, whether the hot‑melt adhesive has sufficient time to fully melt and bond. It also affects wash‑fastness and resistance to peeling.

4. PU heat-transfer film applied to apparel offers elasticity and is resistant to tearing and cracking.
